Reptiles

A diverse group of animals including turtles, lizards, snakes and crocodiles.

Australia is home to about 14% of the world’s reptilian population and has some of the largest known snake and lizard fossils in the world. All reptiles are cold-blooded, have scales and reproduce either by laying eggs or giving birth to live young. Some reptiles are aquatic animals, although most live on land.

The Australian crocodile is the largest living reptile in the world. Also known as the Estuarine or Saltwater Crocodile, adults average at 3 to 5 metres in length! In Australia, Estuarine Crocodiles are found in northern coastal areas, including drainages, rivers, estuaries, creeks, swamps, lagoons and billabongs. Wonder at how these large reptiles are able to return home to their territory after being captured and displaced and learn about the different ways they communicate with each other.

Besides the massive crocodile, geckos are also reptiles. In recent years, numerous new species of gecko have been described, with researchers at the Australian Museum working to understand the relationships and taxonomy of unusual or isolated populations of geckos within New South Wales. Be dazzled by how geckos can regenerate their tail if it gets bitten off by a predator and learn how it can save their life.

Snakes, lizards and other reptiles

Reptiles reproduce either by laying eggs or giving birth to live young.

Many people have a fear of reptiles, particularly snakes. However, reptiles are shy creatures and, if given the chance, will escape rather than attack. Most snakes only bite as a last resort and the majority of bites to humans are inflicted while people are trying to catch or kill them.

All native reptile species are protected within New South Wales.

Reptiles in Sydney

About 40 species of reptiles are found in the Sydney region including turtles, lizards and snakes. As more and more bushland is cleared to accommodate Sydney's increasing population, several reptile species are experiencing population declines and are becoming harder to find.

The Australian Museum respects and acknowledges the Gadigal people of the Eora Nation as the First Peoples and Traditional Custodians of the land and waterways on which the Museum stands.
